Abstract
BACKGROUND This study was designed to evaluate the beneficial effects of a botanical extract combination containing soy isoflavone extract (100mg), Aframomum melegueta seed dry extract (50 mg), and Punica granatum skin dry extract (100mg) on health-related Quality of Life in healthy Spanish menopausal women with hot flashes, anxiety, and depressive symptoms using the validated Cervantes Scale. METHODS AND RESULTS Fifty-seven outpatient women (45-65 years) with menstrual problems associated with climacteric syndrome were enrolled from April 2018 to April 2019 in the context of a prospective, placebo-controlled, double-blind study. Women were randomized to receive treatment with either the botanical combination (250 mg daily divided into two doses) or placebo for eight weeks. At the beginning and end of the study, health-related Quality of Life was assessed using the Cervantes Scale. Subjects treated with the botanical extract, compared to subjects in the placebo group, showed a significant improvement in the Global health-related Quality of Life score (38% [11.3-50.0]% vs. 18.8% [0-37.7]%; P = 0.04) on the Cervantes Scale and, specifically, in the menopause and health domain (13.6% [0-45.4]% vs. 40.7% [20.6-61.0]%; P = 0.05). By contrast, there were no significant changes in the psychic, sexuality, and couple relationship related domains of the Cervantes Scale. Patients who concluded the study did not report substantial side effects. CONCLUSION Short-term intake of the botanical combination improved the Global Quality of Life of climateric women, according to the Cervantes Scale. Since this is a pilot trial, results should be analysed with caution. TRIAL REGISTRATION NCT04381026; ClinicalTrial.gov (retrospectively registered).

Abstract
Some organochlorine pesticides (OCs) have been individually linked to breast cancer (BC) because they exert oestrogenic effects on mammary cells. However, humans are environmentally exposed to more or less complex mixtures of these organochlorines, and the biological effects of these mixtures must be elucidated. In this work we evaluated the in vitro effects exerted on human BC cells by the OC mixtures that were most frequently detected in two groups of women who participated in a BC case-control study developed in Spain: healthy women and women diagnosed with BC. The cytotoxicity, oestrogenicity, and androgenicity of the most prevalent OC mixtures found in healthy women (H-mixture) and in BC patients (BC-mixture) were tested at concentrations that resembled those found in the serum of the evaluated women. Our results showed that both OC mixtures presented a similar oestrogenic activity and effect on cell viability, but BC-mixture showed an additional anti-androgenic effect. These results indicate that although the proliferative effect exerted by these mixtures on human breast cells seems to depend mainly on their oestrogenic action, the BC-mixture might additionally induce cell proliferation due to its anti-androgenic activity, therefore increasing the carcinogenic potential of this mixture. The findings of this study demonstrate that subtle variations in the composition of a mixture may induce relevant changes in its biological action.

Abstract
Fifty-two C-glycosides were synthesized and their in-vitro antiproliferative activity screened against human cervical carcinoma (HeLa) and osteosarcoma (HOS) cell lines. Nine of them had growth inhibitions (GI(50) values) below 10 microM, the C-glucopyranoside 38 being the most active against HeLa (5.4 microM) and the dichlorocyclopropyl derivative 42 against HOS (1.6 microM). Some preliminary structure-activity relationships were established.

Abstract
A phytochemical study has been carried out on the aerial parts of Salvia pachyphylla and S. clevelandii. From S. pachyphylla, the known diterpenes carnosol (2), rosmanol, 20-deoxocarnosol (3), carnosic acid, isorosmanol (4), 7-methoxyrosmanol, 5,6-didehydro-O-methylsugiol (5), 8beta-hydroxy-9(11),13-abietadien-12-one (6), 11,12-dioxoabieta-8,13-diene, and 11,12-dihydroxy-20-norabieta-5(10),8,11,13-tetraen-1-one were isolated, together with the new diterpene pachyphyllone (1). From S. clevelandii, the known diterpenes rosmadial (7), 16-hydroxycarnosol (8), abieta-8,11,13-triene, and taxodone were obtained, together with carnosol (2), rosmanol, and carnosic acid. The structure of the new compound (1) was identified on the basis of spectroscopic data analysis. Several of these compounds (1-8) were evaluated against a small panel of human cancer cell lines.

Abstract
We have demonstrated previously that both rat and human liver microsomes contain a highly specific binding protein for the anabolic steroids stanozolol (ST) and danazol (DA). In this study we solubilized the male rat liver ST-binding protein (STBP) and investigated the following parameters: 1) pharmacological properties, 2) hydrodynamic properties, 3) peptidic composition, 4) the effects of age and hypophysectomy, and 5) inducibility by 17alpha-ethinyl estradiol. We found that STBP is an integral protein bound to the endoplasmic reticulum. 3-[(3-cholamidopropyl)dimethylammonio]-1-propanesulfonate (CHAPS) provided its optimal solubilization without changes in its pharmacological properties, i.e. high specificity for ST and danazol, between natural steroids and ligands of low affinity glucocorticoid-binding sites or of progesterone-binding sites. Hydrodynamic properties of the STBP showed that it has a molecular mass of at least 118 kDa. SDS-PAGE of covalently labeled STBP under nonreducing conditions showed that [3H]ST binds to a 110-kDa protein. The STBP was resolved under reducing conditions into three peptides of 55, 31, and 22 kDa, respectively. STBP increased from immature to adult rats, and it dramatically decreased after hypophysectomy. Unlike the 22-kDa peptide, both the 55- and 31-kDa peptides drastically decreased in both immature and hypophysectomized rats. 17alpha-Ethinyl estradiol administration to immature or hypophysectomized rats induced the 55- and 31-kDa [3H]STBP to a greater extent than the 22-kDa peptide. Thus, STBP appears as an oligomeric protein composed of hormone-regulated peptides. The availability of solubilized STBP and the fact that it can be induced in vivo represent major steps toward the purification and functional significance of this unique steroid-binding protein.
